Gameplay
Dead Trigger 2 is a zombie-apocalypse-themed first-person shooter with survival horror and action role-playing elements, currently available on iOS, Android and recently on Windows Phone 8.1 mobile devices. Running on the Unity game engine, the game features a progression system, numerous environments, unlockable and upgradable weapons, and various story-based and quick-play mission types.
Dead Trigger 2 is a free-movement shooter; rather than the on-rails gameplay typical of mobile zombie shooters, the player controls the character's movement like a typical console or PC FPS. The game features two dramatically different control paradigms; with the default controls, the player merely aims at zombies - their weapons will attack automatically when a zombie is underneath the crosshair. The advanced control scheme functions like the first game - the player presses a button to fire the weapon, and an additional button lets the player aim down the weapon's sights for increased accuracy.
Gameplay typically revolves around completing objectives while killing zombies (occasionally killing zombies is the only objective). It also has an infinite wave of zombies in the arena of death. There are also different campaigns and tournaments. The player has a limited amount of health that is refreshed at the start of each mission. The player loses health when hit by zombies or by certain environmental hazards (i.e. radiation). The player can regain health by taking healing pills or getting a health power up from a special zombie.
Enemies come in two flavors, standard zombies and special zombies. Standard zombies often plod along at a slow pace and attack with their arms, but some may sprint or carry melee weapons for increased damage. Special zombies have distinct appearances and unique traits; they are deadlier and tougher to kill, but drop blueprints or large amounts of cash (and sometimes health) when killed.
In addition to carrying two primary weapons, the player also carries a melee weapon and up to three types of consumable items. Consumables include health pills, grenades, exploding chickens and others.
The storyline involves 5 campaigns, each set in a different continent:
USA campaign
Africa campaign
China campaign
Europe campaign
South America campaign
